IC63 - The Ghost of Cassiopeia (Bortle 8 Backyard)

IC63, also known as the Ghost of Cassiopeia, is located in this northern circumpolar constellation right next to one of its main stars, Navi (Gamma Cas) at the center of the "W" asterism. This star is a multiple system and it is also variable in brightness, with a mass that is 19 times that of the sun and a brightness 65000 times more intense. It also rotates very fast, more than 200 times faster than our own sun. It is a sub-giant star that has reached the age at which it is consuming most of its core hydrogen and it will turn into a giant star. It is located at around 550 light years away from Earth.

IC63, the ghost-looking nebula close to it, is a nebula that is being bombarded by radiation from the proximity of Navi. This radiation makes the hydrogen in the cloud emit light as it gets excited, which explains the strong response when imaged with an Ha filter. But there is also quite a bit of broadband response in RGB, with some areas showing a strong response in the blue part of the spectrum. This makes this nebula a hybrid emission / reflection nebula. The reflection portion is dust in the nebula reflecting light from Gamma Cassiopeiae. IC63 itself is part of a larger set of nebulae spawning over 2 degrees of sky including IC59 which is primarily a reflection nebula.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
